Certain Officers.

On April 28, 2026, United

Community Banks, Inc. (the “Company”) and Jefferson L. Harralson (the “Executive”) entered into an Agreement

dated as of April 28, 2026 (the “Harralson Agreement”) pursuant to which Executive

will resign, effective as of December 31, 2026 (the “Employment Termination Date”), as Executive Vice President and Chief

Financial Officer of the Company. The following summary of the material terms of the Harralson Agreement is qualified in its

entirety by reference to the full text of the Harralson Agreement, a copy of which accompanies this Current Report on Form 8-K as

Exhibit 10.1 and is incorporated herein by this reference.

The Harralson Agreement provides that the Executive’s

employment with the Company is at-will and will continue until: (a) the close of business on the Employment Termination Date; or

(b) such earlier date on which Executive’s employment with the Company is terminated by the Executive’s death

or disability, by the Company for Cause or by the Executive’s voluntary resignation, at any of which

time(s) his employment with the Company shall terminate (the “Separation Date”). The Harralson Agreement provides

for the Executive, through the Employment Termination Date, to receive his regular monthly salary and automobile allowance, to participate

in the Company’s employee benefit plans and receive reimbursement of expenses incurred on behalf of the Company. If the Executive’s

employment continues through the Employment Termination Date, he also will receive his 2026 incentive bonus, when determined, and a cash

severance of $1 million (the “Severance”), payable no later than January 15, 2027.

If the Executive’s employment

is terminated prior to the Employment Expiration Date as a result of a voluntary resignation or a termination by the Company for Cause,

the Executive shall have no rights under the Harralson Agreement except to receive any accrued but unpaid salary through the Separation

Date. If the Executive’s employment is terminated prior to the Employment Expiration Date as a result of disability, the Executive

shall have no rights under the Harralson Agreement except to receive any accrued but unpaid salary through the Separation Date, his 2026

incentive bonus, when determined, and a prorata portion of the Severance, reduced by $125,000 for each full month remaining between the

date of disability and December 31, 2026. If the Executive’s employment is terminated prior to the Employment Expiration

Date by the Company without cause, the Executive shall receive all of the benefits under the Harralson Agreement as if he continued to

be employed through the Employment Termination Date.

In addition, as of the Employment Termination Date, the Executive will

satisfy the early retirement eligibility criteria under the Company’s Modified Retirement Plan pursuant to his participation agreement.

Accordingly, the Executive will be entitled to receive his minimum early retirement benefit of $70,000 annually, payable as a life annuity,

or as adjusted if an alternative payment method is elected, in accordance with the terms of the plan.

Reference is made to that certain Change in Control Continuity Agreement

dated February 14, 2023 (the “Retention Agreement”) (incorporated herein by reference to Exhibit 10.2 to the Company’s Current Report on Form 8-K dated February 14, 2023 and filed with the U.S. Securities and Exchange Commission on February 14, 2023). The Retention Agreement shall terminate on the Separation Date and

neither the Company nor the Executive shall have any further rights or obligations thereunder. Following the Separation Date,

the respective rights and obligations of the parties shall be governed by the terms of the Harralson Agreement; provided, however, that

notwithstanding the foregoing, in the event Executive, prior to the Separation Date becomes eligible for benefits pursuant to Section 4

of the Retention Agreement, then the Harralson Agreement cease to be effective and Executive shall receive only the benefits provided

by the Retention Agreement.

The Harralson Agreement also contains customary non-disparagement,

non-solicitation and confidentiality provisions. Upon the Employment Termination Date, in order to receive the remaining benefits

under the Harralson Agreement, the Executive also must execute and deliver a release, in the form attached to the Harralson Agreement,

of all claims that he might have against the Company.

release of claims, all upon the terms set forth herein;

THEREFORE, in consideration of the premises and

mutual promises contained in this Agreement, Executive and UCBI agree as follows:

1.             Termination

Date”). The Retention Agreement shall terminate on the Separation Date and neither UCBI nor the Executive shall have

any further rights or obligations thereunder.  Following the Separation Date, the respective rights and obligations of the

parties shall be governed by the terms of this Agreement; provided, however, that notwithstanding the foregoing, in the

event Executive, prior to the Separation Date becomes eligible for benefits pursuant to Section 4 of the Retention Agreement, then

this Agreement shall cease to be effective and Executive shall receive only the benefits provided by the Retention Agreement.

2.             Payments

or other regulatory guidance issued under such statutory provision and without any diminution in the value of the payments to the Executive.  Notwithstanding

the foregoing, under no circumstance shall UCBI be responsible for any taxes, penalties, interest or other losses or expenses incurred

the terms of the any applicable UCBI clawback and/or recoupment policy (including, without limitation, the Policy Relating the Recovery

survive the termination of Executive’s employment for any reason. The foregoing remedy is in addition to and separate from any other

relief available to the Company due to Executive’s misconduct or fraud. Executive agrees to return promptly any such compensation

identified in good faith by UCBI by written notice provided. Subject to applicable law, if Executive fails to return such compensation

promptly, he agrees that the amount of such compensation may be deducted from any and all other compensation owed to him by UCBI.

- 2 -

or otherwise), subsidiaries, affiliated entities, divisions and assigns, together with each and every of their present, past and future

officers, directors, shareholders, general partners, limited partners, employees and agents and the heirs and executors of same (herein

collectively referred to as the “Company Group”) has breached any oral or written contract that may have existed

between Executive and UCBI or any member of the Company Group with respect to his employment or termination of employment nor has any

of UCBI or any member of the Company Group, violated any law, statute, rule regulation or ordinance of any governmental authority

relating to Executive’s employment.  Executive acknowledges that the payments and other consideration paid hereunder can

not and shall not be construed as any admission of liability or wrongdoing on the part of either UCBI or any member of the Company Group.  Executive

further acknowledges and agrees that the payments and other benefits being received by him pursuant to this Agreement satisfy any claim

that he might have had under the Retention Agreement or any other UCBI policy or practice.  Executive understands that the Release

extends to all of the aforementioned claims and potential claims which arose on or before the date of the execution of this Agreement

and that may arise on or before the Employment Termination Date, whether now known or unknown, suspected or unsuspected, and his participation

as a member of any class asserting any such claims, and that this acknowledgement constitutes an essential term of this Agreement.   Executive

understands and acknowledges the significance and consequence of this Agreement and of each specific release and waiver, and expressly

consents that this Agreement shall be given full force and effect according to each and all of its express terms and provisions, including

those relating to unknown and unsuspected claims, demands, obligations, and causes of action, if any, as well as those relating to any

other claims, demands, obligations or causes of action herein above-specified. Executive further confirms that he has not reported

internally to UCBI any allegations of wrongdoing by UCBI or its officers, including any allegations of corporate fraud, and that he has

not been retaliated against for reporting or objecting to any such allegations internally to UCBI.

(d)           Collective/Class Action

Waiver. If any claim is not subject to release, to the extent permitted by law, Executive hereby waives any right or ability to

be a class or collective action representative or to otherwise participate in any putative or certified class, collective or multi-party

action or proceeding based on such a claim in which UCBI or any member of the Company Group is a party.

(e)           Non-Disparagement.

Executive agrees that he shall not, before or after the Separation Date, directly or indirectly, make or authorize any disparaging or

defamatory statements regarding UCBI, any member of the Company Group or UCBI’s customers or vendors including, without limitation,

disparagement shall include communicating or disclosing any information or communications to anyone or any entity which is intended to

or has the effect of having any negative impact on the business or reputation of UCBI or any member of the Company Group in the marketplace

or otherwise. To the extent that the foregoing prohibition might be applicable, it is not intended

to prevent Executive from giving testimony pursuant to compulsory process of law.  In determining what constitutes “compulsory

process of law,” Executive may rely on advice of counsel of his choice and his expense.

(f)            Non-Solicitation.

Executive recognizes and acknowledges that, as a result of his employment by and position with UCBI,

he has become familiar with and has acquired knowledge of confidential information and certain other information regarding the other executives

and employees, and of the customers and vendors, of UCBI and the Company Group.  Therefore, Executive agrees that, during the

twenty-four (24) month period (the “Non-solicitation Period”) following the Separation Date, Executive shall

not encourage, solicit or otherwise attempt to persuade any person in the employment of UCBI or any member of the Company Group to end

his/her employment with UCBI or any member of the Company Group or to violate any confidentiality, non-competition or employment agreement

that such person may have with UCBI or any member of the Company Group or any policy of UCBI or any member of the Company Group.  Furthermore,

Executive agrees that, during the Non-solicitation Period, Executive shall not encourage, solicit or otherwise attempt to persuade any

person that is a customer or vendor of UCBI or any member of the Company Group to make any change in their business relationship with

UCBI or any member of the Company Group. Additionally, as to employees of UCBI or any member of the Company Group, neither Executive nor

any person acting in concert with Executive (and with Executive’s knowledge) shall, during the Non-solicitation Period, employ any

person who has been employee (above branch-level manager) of UCBI or any member of the Company Group unless that person has ceased to

be an employee of UCBI or a member of the Company Group for at least six (6) months.  Executive also shall not communicate

in any manner whatsoever, whether directly or indirectly, with any executive employee of UCBI or any member of the Company Group on the

topic of the individual's employment with UCBI or any member of the Company Group, his or her plans for employment in the future, or his

or her employment with any other entity, other than to say Executive is unable to engage in any such discussions. Executive may request

that the restrictions set forth in this Section 3.(f) be waived as to any employee whose employment has been involuntarily terminated

by UCBI; provided, however, that the decision whether to waive such restriction shall be in UCBI’s sole discretion

and shall not be binding upon UCBI unless such waiver is evidenced by a written agreement that has been executed and delivered by, and

is legally binding on, UCBI and the Executive, which, if agreed to by UCBI, may also include terms and conditions that UCBI in its sole

discretion are reasonably necessary under the circumstances. Executive and UCBI recognize

and acknowledge that the scope, area and time limitations contained in this Section 3.(f) are reasonable and are properly required

for the protection of the business interests of UCBI due to Executive's status and reputation in the industry and the knowledge acquired

and to be acquired by Executive through his association with UCBI’s business and the public's close identification of Executive

with UCBI.  Executive acknowledges and understands that his continuing employment through the Separation Date as well as the

payments and benefits provided Executive pursuant to the Agreement as consideration for his execution of this Agreement and his agreement

with the terms of the foregoing non-solicitation covenant.

- 3 -

of Counsel. Executive represents and warrants that he: (i) has carefully read this

Agreement; (ii) understands its contents, meaning and intent; (iii) understanding this document, has freely and voluntarily

executed it with the advice of counsel, without compulsion, coercion or duress

5.             PROTECTED

RIGHTS; MONETARY AWARDS.

(a)           Reporting

the National Labor Relations Board, the Occupational Safety and Health Administration, the Securities and Exchange Commission (“SEC”),

to either house of the U.S. Congress, to an Inspector General, to the U.S. Department of Justice or any other federal, state or local

governmental agency or commission (each a “Governmental Entity”); or

(ii) Executive’s ability to communicate with any Governmental Entity or otherwise participating, testifying

or assisting in any investigation, hearing or other proceeding that may be brought by, in conjunction with, or otherwise under

provided to any Governmental Entity under such law or regulation. Executive is also not required to notify or obtain permission from UCBI

when filing a governmental whistleblower charge or complaint or engaging or participating in protected whistleblower activity. Notwithstanding

the foregoing, however, Executive does herby waive, to the extent permitted by law, Executive’s right to any monetary recovery

should any Governmental Entity (such as the Equal Employment Opportunity Commission) pursue any claims

on his behalf, except for any rights Executive may have to receive a payment from a Governmental Entity
